OK, here's what the 12 year old Cathemat learned:
From Mishat, the Dalati Wizard, Cathemat learned that the Gods of the West probably refer to the Living Gods of the Halcyon Sea Region, far to the west of Zeium Dalat. He was surprised at the question, but delighted to fill Cathemat in on the details; each god in that region was ruler of a single city, and they were related in a complex pantheon. Mishat had a good chuckle when he told Cathemat that people from the Halcyon Sea Region occasionally travel east to Zeium Dalat, believing it to be their fabled City of Plenty (their afterlife). This, according to the mage, is all the proof you need of Dalati superiority.
Sands, the Pon warlock brushed Cathemat off, although Cathemat got the sense he didn't know anything about the Gods of the West.
Proudeye, a Spirit Shaman with a scarred face and unknown ethnicity had a twitch in his eye as Cathemat asked him about the Gods of the West. He asked, quite pointedly, whether Cathemat had spoken of this with anyone else - when Cathemat told him he talked to Mishat, Proudeye spat, then told Cathemat "whatever they are, they can't be very important, can they?"
Ekilar, the Nubalese mystical lyricist didn't know anything Mishat hadn't already said about the Gods of the West, but was able to relate a mournful song from the Halcyon city of Isra about the spirits blowing away like dust. The memory of that song, and the sense of desolation which it evoked when Ekilar sang it, is a crystal-clear memory for Cathemat.
